While on a business trip, Yumi finds herself increasingly aroused despite the successful progress of her work. She forcefully invites her subordinate Murata to a hot spring, where he is tormented by her habitual workplace harassment, surrendering his body as a way to relieve stress. Meanwhile, another subordinate, Shioi, observes the situation and, seeking to vent his long-suppressed frustrations, joins in. After a long hiatus from sex, Yumi is driven to madness as she is repeatedly made to climax, receiving endless creampie after creampie that shows no sign of stopping.
